changelog

Intel XScale PXA255 引导Linux的Redboot 版bootloader源代码！

	The great renaming.  All platform references are now EDB7xxx, except
	for CL7111 (archaic) which remains.  This required renaming of the
	whole directory, along with many internal files.

1999-11-12  Gary Thomas  <[e-mail]>

	* tests/dram_test.c: Make more generic (no platform dependencies).

	* src/cl7211_misc.c (hal_clock_reset): Implement "bus idle" code
	which helps with DRAM refresh problem.
